Bartlein Barrel - SS, 6mm, B#11 Medium Palma

Unlock the secrets of precision shooting with the Bartlein Barrel - SS, 6mm, B#11 Medium Palma. Discover how different factors, including barrel contours, rifling, and fluting, can influence the performance of your rifle barrel.

Do Contours Affect Barrel Weight and Performance?

Yes, barrel contours play a crucial role in determining both weight and performance. Heavier contours can offer advantages, especially in resisting heat-induced barrel movement during extended shooting sessions. Bartlein Barrels specializes in single point cut rifling, reducing stress in the barrel blank and making the contour less critical compared to button-made barrels.

Does Barrel Contour Impact Shooting?

Barrel contour does affect shooting performance. A heavier barrel can often lead to better shooting results by helping shooters manage recoil and reduce fatigue during extended shooting sessions. However, Bartlein Barrels has observed that lighter weight contours can also perform exceptionally well, challenging the belief that a heavier contour is always critical.

Suppressor Compatibility and Barrel Contour

When using a suppressor, it's typically recommended to pair it with a heavier barrel contour. This combination enhances shooting performance by stabilizing the barrel's harmonic vibrations. Bartlein Barrels suggests avoiding suppressors on barrels with contours smaller than medium palma for optimal results.

Advantages of Single Point Cut Rifling

Bartlein Barrels' commitment to single point cut rifling ensures minimal stress in the barrel blank. Unlike button rifling, which can induce significant stress and bore size changes as contours get smaller, single point cut rifling maintains consistent performance without compromising accuracy. Threaded muzzle crown edges remain stable for precision shooting.

Importance of Fluting a Barrel

Fluting a barrel offers several benefits, including weight reduction, improved barrel cooling, and an aesthetic appeal that many customers appreciate. It doesn't alter the contour but enhances the barrel's overall performance.

Frequently Asked Questions about Fluting

  • Minimum Depth for Fluting: It's important not to flute barrels too deep, as excessive fluting can lead to harmonic and vibration issues that may affect accuracy.
  • Does Fluting Make the Barrel Stiffer? Fluting may slightly reduce the stiffness of the barrel, but the impact on stiffness varies based on measurement methods and is generally not significant.

Rifling Types and Their Impact

Bartlein Barrels offers three rifling types: 4-groove, 5R, and Conventional-5. The number of grooves doesn't significantly affect accuracy or barrel life. The 5R rifling style, with its gentler angles, can help prevent bullet failure and improve bullet flight.

Additional Benefits of 5R Rifling

The 5R rifling style has been shown to reduce bullet failure and enhance bullet flight. It offers a distinct advantage with its gentler land angles, which deform bullets less during the transition from case to rifling.

Exceptions to Consider

While 5R rifling is generally beneficial, short jacket 6mm bullets used by short-range bench shooters (typically 65-68gr) may not perform optimally with this rifling style. Bartlein Barrels has observed limitations in group sizes for these specific bullets, especially when using boat tail designs.
